Abstract:
Camera Canvas is an image editing software package for users with
severe disabilities.  It is specially designed for Camera Mouse, a
camera-based mouse-substitute input system for people with limited
mobility.  Users can manipulate images through various head movements,
tracked by Camera Mouse.  The system is also fully usable with
traditional mouse or touch-pad input. Designing the system, we studied
the requirements and solutions for image editing and content creation
when using Camera Mouse.  Experiments with 20 subjects, each testing
Camera Canvas with Camera Mouse as the input mechanism, showed that
users found the software easy to understand and operate.  User
feedback was taken into account to make the software more usable and
the interface more intuitive.  We suggest that the Camera Canvas
software makes important progress in providing a new medium of utility
and creativity in computing for users with severe disabilities.
